This is an arithmetic progression with a first term of 1, a difference of 1, last term (and number of terms) 105.
→ sum = ½ × number_of_terms × (first_term + last_term)
= ½ × 105 × (1 + 105)
= ½ × 105 × 106
= 5565

What is 103 plus 2?
103 + 2 = 105
If x -1 the value of (-4)(x) plus (2)(x)?
It is 2.
How do you add the following mixed numbers 3 and 2 over 7 plus 7 and 1 over 15?
3 and 2 over 7 = ( 3*7 + 2 )/ 7 = 23/7 7 and 1 over 15 = ( 7*15 + 1 ) / 15 = 106/15 The least common multiple of 7 and 15 is 105 So, 23/7 + 106/15 = 23*15 / 105 + 106*7 / 105 = 345 / 105 + 742 / 105 = 1087 / 105 = (1050 + 37 ) / 105 = 10 and 37 over 105
If 3x - 1 equals 11 what is the value of x 2 plus x?
If 3x - 1 = 11 what is the value of x 2 + x?
- If 3X - 1 equals what is the value of X2 plus X?
- If 3X - 1 = 11, what is the value of X^2 + X?
What is 1 plus 2 plus 3 plus 99?
105
What is value of 1 plus cosθ?
It has to be between zero and 2, but the exact value depends on the value of Θ .
What is the exact value of tan 105 degrees?
To find the exact value of tan 105°. First, of all, we note that sin 105° = cos 15°; and cos 105° = -sin 15°. Thus, tan 105° = -cot 15° = -1 / tan 15°. Using the formula tan(α - β) = (tan α - tan β) / (1 + tan α tan β); and using, also, the familiar values tan 45° = 1, and tan 30° = ½ / (½√3) = 1/√3 = ⅓√3; we have, tan 15° = (1 - ⅓√3) / (1 + ⅓√3); whence, cot 15° = (1 + ⅓√3) / (1 - ⅓√3) = (√3 + 1) / (√3 - 1) {multiplying through by √3} = (√3 + 1)2 / (√3 + 1)(√3 - 1) = (3 + 2√3 + 1) / (3 - 1) = (4 + 2√3) / 2 = 2 + √3. Therefore, tan 105° = -cot 15° = -2 - √3, which is the result we sought. We are asked the exact value of tan 105°, which we gave above. We can test the above result to 9 decimal places, say, by means of a calculator: -2 - √3 = -3.732050808; and tan 105° = -3.732050808; thus indicating that we have probably got the right result.
What can you multipy to get 105?
105 is divisible by 5 because it ends in a 5. 105/5 = 21, so 5*21=105. Since 21 = 3*7, and 5*3=15 and 5*7=35, 15*7 = 105 and 35*3 = 105 too. Also, 105 * 1 = 105. 210 * 1/2 = 105, 315 * 1/3 = 105, etc. Here I multiplied 105 by 2 or 3 and then multiplied back by 1/2 or 1/3.
What is the value of 2 x 0 x 1 plus 1?
2 x 0 x 1 + 1 = 0 + 1 = 1
What is the value of x if -8x 1 3x-2-3x 2?
Without an equality sign and not knowing the plus or minus values of 1 and 2 the value of x can't be worked out
What Is The Smallest Value Of k For 420k To Be A Perfect Square?
The prime factorization of 420 is 2 x 2 x 3 x 5 x 7. You need another 3 x 5 x 7 (105) to make that a perfect square. The question should stipulate integral values. If k was 1/105 or 1/420, the value would also be a perfect square.
What is the value of x if x plus two equals one?
If: x+2 = 1 then x = -1
What is 2 over 3 plus 5 over 7 plus 2 over 5?
figure it out ur self ******************** 2/3 + 5/7 + 2/5 Make each of the denominators the same, by finding the LCD, i.e. 105. To make 2/3 have a denominator of 105, multiply it by 35/35. Similarly, multiply 5/7 by 15/15, and 2/5 by 21/21. Therefore, 2/3*35/35 + 5/7*15/15 + 2/5*21/21 = 70/105 + 75/105 + 42/105 = (70 + 75 + 42)/105 = 187/105
If a3 plus 2 under root 2then find the value of a square plus 1 upon a square?
It is 34.
What are the common factors of 8 and 105?
The easiest way to figure this out is to get the factors of 8 and see if they are factors of 105. Factors of 8: 8, 4, 2, 1 Now check, 105/8 = 13.125 (not a factor) 105/4 = 26.25 (not a factor) 105/2 = 52.5 (not a factor) 105/1 = 105 (is a factor) So the common factor of 8 and 105 is 1.
If 1 plus 1 equals 2 2 plus 2 equals 22?
no if 1 plus 1 equals 2 then 2 plus 2 equals 4.
